Failure to use the proper coolant can dam-
age your cooling system. Your authorized
SUZUKI dealer can help you select the
proper coolant.
Coolant Level CheckCheck the engine coolant level at the
reserve tank, not at the radiator. With the
engine cool, the engine coolant level
should be between the “FULL” and “LOW”
marks.Adding Coolant
56KN090
If the engine coolant level is below the
“LOW” mark, more engine coolant should
be added. Remove the reserve tank cap
and add engine coolant until the reserve
tank level reaches the “FULL” mark. Never
fill the reserve tank above the “FULL” mark.
CAUTION
To avoid damaging your cooling sys-
tem:
 Always use a high quality ethylene
glycol base phosphate type coolant
diluted with distilled water at the
correct mixture concentration.
 Make sure that the proper mix is 50/
50 coolant to distilled water and in
no case higher than 70/30. Concen-
trations greater than 70/30 coolant
to distilled water will cause over-
heating conditions.
 Do not use straight coolant nor
plain water (except SUZUKI LLC:
Super (Blue)).
 Do not add extra inhibitors or addi-
tives. They may not be compatible
with your cooling system.
 Do not mix different types of base
coolants. Doing so may result in
accelerated seal wear and/or the
possibility of severe overheating
and extensive engine/CVT damage.
WARNING
Engine coolant is harmful or fatal if
swallowed or inhaled. Do not drink
antifreeze or coolant solution. If swal-
lowed, do not induce vomiting. Imme-
diately contact a poison control
center or a physician. Avoid inhaling
mist or hot vapors; if inhaled, remove
to fresh air. If coolant gets in eyes,
flush eyes with water and seek medi-
cal attention. Wash thoroughly after
handling. Solution can be poisonous
to animals. Keep out of the reach of
children and animals.
CAUTION
SUZUKI LLC: Super (Blue) coolant;
SUZUKI LLC: Super (Blue) coolant is
already diluted to the proper percent-
age. Do not dilute with distilled water
additionally. Doing so may result in
the possibility of freezing coolant
and/or overheating.

Coolant ReplacementSince special procedures are required, we
recommend you take your vehicle to your
SUZUKI dealer for coolant replacement.
Air Cleaner
80J2056
If the air cleaner is clogged with dust, there
will be greater intake resistance, resulting
in decreased power output and increased
fuel consumption.
Unclamp the side clamps, and remove the
element from the air cleaner case. If it
appears to be dirty, replace it with a new
one.
Spark PlugsYou should inspect spark plugs periodically
for carbon deposits. When carbon accu-
mulates on a spark plug, a strong spark
may not be produced. Remove carbon
deposits with a wire or pin and adjust the
spark plug gap.
To access the spark plugs,
80J2069
1) Remove the air cleaner inlet hose (1).
Remove the front part (2), then remove
the rear part (3) of the air cleaner case.
CAUTION
SUZUKI LLC: Standard (Green)
coolant;
 The mixture you use should con-
tain 50% concentration of anti-
freeze.
 If the lowest ambient temperature
in your area is expected to be
–35°C (–31°F) or below, use higher
concentrations up to 60% following
the instructions on the antifreeze
container.
CAUTION
When putting the cap on the reser-
voir tank, line up the mark on the cap
and the mark on the tank. Failure to
follow this can result in coolant leak-
age.
CAUTION
The air cleaner element should be
replaced every 50000 km (30000
miles). More frequent replacement is
necessary when you drive under
dusty conditions.
CAUTION
When remove the engine cover, make
sure the cover does not interfere the
vehicle to avoid damage to the cover.

EXAMPLE
CAUTION
 When servicing the iridium/plati-
num spark plugs (slender center
electrode type plugs), do not touch
the center electrode, as it is easy to
damage.
 When installing the spark plugs,
screw them in with your fingers to
avoid stripping the threads. Tighten
with a torque wrench to 25 Nm (2.5
kg-m, 18.0 lb-ft). Do not allow con-
taminants to enter the engine
through the spark plug holes when
the plugs are removed.
 Never use spark plugs with the
wrong thread size.
CAUTION
When replacing spark plugs, you
should use the brand and type speci-
fied for your vehicle. For the speci-
fied plugs, refer to the
“SPECIFICATIONS” section at the
end of this book. If you wish to use a
brand of spark plug other than the
specified plugs, consult your SUZUKI
dealer.

Gear Oil Level CheckThe manual transaxle, transfer gears (i-
AWD CVT) and rear differential (i-AWD)
are lubricated with gear oil. To check the
gear oil level in any of the above locations,
use the following procedure:
1) Park the vehicle on a level surface. Set
parking brake and stop the engine.
2) Remove the oil filler plug (1).
For the manual transaxle;
3) If gear oil flow from the plug hole, the oil
level is correct. Reinstall the plug.
If gear oil do not flow from the plug
hole, add oil through the filler plug hole
until a little oil flow from the plug hole.
For the transfer and rear differential;
3) Check the inside of the hole with your
finger. If the oil level comes up to the
bottom of the plug hole, the oil level is
correct. If so, reinstall the plug.
4) If the oil level is low, add gear oil
through the filler plug hole (1) until the
oil level reaches the bottom of the filler
hole.Gear Oil ReplacementSince special procedures, materials and
tools are required, it is recommended that
you trust this job to your authorized
SUZUKI dealer.
Clutch Pedal

GREEN-1 or Shell GREEN-1V.Fluid Level CheckYou must check the fluid level with the CVT
fluid at normal operating temperature.
To check the fluid level:
1) To warm up the transaxle fluid, drive the
vehicle or idle the engine until the tem-
perature gauge indicates normal oper-
ating temperature.
2) Then drive for ten more minutes.
NOTE:
Do not check the fluid level if you have just
driven the vehicle for a long time at high
speed, or if you have driven in city traffic inhot weather. Wait until the fluid cools down
(about 30 minutes), or the fluid level indica-
tion will not be correct.
3) Park your vehicle on level ground.
4) Apply the parking brake and then start
the engine in “P” (Park). Let it idle for
two minutes and keep it running during
the fluid level check.
5) With your foot on the brake pedal, move
the gearshift lever through each gear,
pausing for about three seconds in
each range. Then move it back to the
“P” (Park) position.

6) The handle of the CVT fluid dipstick is
colored red or orange for easy identifi-
cation.
Remove the dipstick, clean it and push
it back in until the cap seats. Pull out
the dipstick and read the fluid level.
The fluid level should be between the
two marks in the “HOT” range on the
dipstick.
7) Add just enough specified fluid through
the dipstick hole to fill the transaxle to
the proper level. It takes only 0.6 liters
(1.27 US pt) for CVT to raise the level
from “LOW” to “FULL”.Deterioration Checking or Chang-
ing OilSince special procedures, materials and
tools are required to check the deteriora-
tion of CVT oil or change, it is recom-
mended that you trust this job to your
authorized SUZUKI dealer.
BrakesBrake Fluid
80J004
Check the brake fluid level by looking at
the reservoir in the engine compartment.
Check that the fluid level is between the
“MAX” and “MIN” lines. If the brake fluid
level is near the “MIN” line, fill it up to the
“MAX” line with SAE J1703 or DOT3 brake
fluid.
80J104
CAUTION
After checking or adding oil, be sure
to insert the dipstick securely.
EXAMPLE
WARNING
Failure to follow the guidelines below
can result in personal injury or seri-
ous damage to the brake system.
 If the brake fluid in the reservoir
drops below a certain level, the
brake warning light on the instru-
ment panel will come on (the
engine must be running with the
parking brake fully disengaged.)
Should the light come on, immedi-
ately ask your SUZUKI dealer to
inspect the brake system.
 A rapid fluid loss indicates a leak in
the brake system which should be
inspected by your SUZUKI dealer
immediately.
 Brake fluid can harm your eyes and
damage painted surfaces. Use cau-
tion when refilling the reservoir.

NOTE:
With disc brakes, the fluid level can be
expected to gradually fall as the brake
pads wear.Brake Pedal
65D345
With the engine running and the parking
brake set, measure the distance between
the brake pedal and floor carpet when the
pedal is depressed with approximately 300
N (66 lbs, 30 kg) of force. The minimum
distance required is as specified. Since
your vehicle’s brake system is self-adjust-
ing, there is no need for pedal adjustment.
If the pedal to floor carpet distance asmeasured above is less than the minimum
distance required, have your vehicle
inspected by your SUZUKI dealer.
NOTE:
When measuring the distance between the
brake pedal and floor wall, be sure not to
include the floor mat or rubber on the floor
wall in your measurement.

WARNING
(Continued)
 Do not use any fluid other than SAE
J1703 or DOT3 brake fluid. Do not
use reclaimed fluid or fluid that has
been stored in old or open contain-
ers. It is essential that foreign parti-
cles and other liquids are kept out
of the brake fluid reservoir.
WARNING
Brake fluid is harmful or fatal if swal-
lowed, and harmful if it comes in con-
tact with skin or eyes. If swallowed,
do not induce vomiting. Immediately
contact a poison control center or a
physician. If brake fluid gets in eyes,
flush eyes with water and seek medi-
cal attention. Wash thoroughly after
handling. Solution can be poisonous
to animals. Keep out of the reach of
children and animals.
